scribbled a couple of lines to Sir Bernard, at Hove, informing him of the mysterious affair. This I folded and placed in my pocket in readiness for the re-opening of the telegraph office at eight o'clock. Shortly afterwards we heard the wheels of the cab outside, and a few minutes later were joined by a police inspector in uniform and an officer in plain clothes. In a few brief sentences I explained to them the tragic circumstances, and then led them upstairs to the dead man's room.
